on last weekends ride my friend has an 02 zr 600 efi with about 320 miles on it. half way into the day the sled stopped and aroubd 4000 rpm it would miss and hessatate. you also could hear the fuel pump working hard. Towed it back, called the dealer and was told that cat found the tanks were getting shavings in the tank and plugging the filters. so we pulled the filters and cleaned them w/carb spray. worked good for 10 minutes and the problem was back. anyone else have this problem. Is it a problem with this machine and cat won't notify the owner? Yes its under warranty but he did loose 2 days riding. i haven't heard the fix yet but i will post it.
